General Fatigue library
Project description
pyLife – a general library for fatigue and reliability
pyLife is an Open Source Python library for state of the art algorithms used in lifetime assessment of mechanical components subject to fatigue load.
Purpose of the project
This library was originally compiled at Bosch Research to collect algorithms needed by different in house software projects, that deal with lifetime prediction and material fatigue on a component level. In order to further extent and scrutinize it we decided to release it as Open Source. Read this article about pyLife's origin.
So we are welcoming collaboration not only from science and education but also from other commercial companies dealing with the topic. We commend this library to university teachers to use it for education purposes.
Disclaimer
The develop
branch is at the moment undergoing heavy development for the
pylife-2.0
release. Check out NEWS-2.0.md for details. That
means that breaking changes are likely to occur. If you are new to pyLife, it
is nevertheless worthwhile following the develop
branch, as it stabilizes in
the upcoming months. The way things are done are and will be a huge
improvement over pylife-1.x
.
